You and Tsukishima have known each other since you were practically born, as his mother and yours were friends before that. You would go to his house almost every weekend to eat or go out to play, you were very close to each other.

You both entered the same high school; Karasuno. You were together most of the time, until recently you met Tobio, who was Tsukishima's teammate on the same school volleyball team.

You started spending a lot of time with Tobio, and Tsukishima saw that, his blood heated up and he got moody whenever you talked to him about your new friend. Tsukishima felt jealous, but... why? if you two aren't even in a relationship?

...

The bell rang, indicating that it was time for lunch. Everyone quickly left class and you started packing your things to get ready to go with Tobio. When you finished, you stood up from your seat and headed towards the exit, when suddenly a voice stopped you.

—"Wait." It was Tsukishima's voice. You turned around and saw him a few steps behind you. You wondered what he wanted.
